Barthel, 8434 W. th, Lakewood, Colo. 80215 Filed Dec. 21, 1967, Ser. No. 692,364 Int. Cl. A471 5/00 US. Cl. -339 1 Claim ABSTRACT OF THE DISCLOSURE The present invention relates to an attachment for drilling equipment for deflecting away from the immediate area materials such as dust and other fine particles that collect in the immediate area from the action of the drilling equipment. The drilling equipment is used on rock and other similar material. An object, therefore, of the present invention is to provide an attachment for drilling equipment for use on rock and other material to deflect away from the immediate area the resulting dust, and to construct the attachment as a basic structure from steel, tin sheets, plastic sheets, or other hard material such as hard rubber and the like. Miscellaneous materials such as felt and spring steel or coil springs, are used for other various parts of the attachment.

The above and other objects and advantages of the invention will become apparent upon full consideration of the following detailed description and accompanying drawings in which:

FIGURE 1 is a generally perspective view of the attachment for drilling equipment according to the preferred embodiment of the present invention;

FIGURE 2 is a further perspective view of reduced size showing the attachment in an open position; and

FIGURE 3 is a top or plan perspective view of FIG- URE 1, and showing also certain features of the interior and of the fastener face of the attachment, according to the preferred embodiment of the present invention.

Referring now to the drawings, there is shown a mating construction 10 formed of a front and rear open boxes 12, 14, the boxes 12, 14 being joined on a common edge by a piano hinge 16. There is an opening 18 in the box 12 for drilling equipment, and this forms the front face of the mating construction. The opening 18 in box 12 is the outlet used to attach the vacuum hose which car- 3,499,181 Patented Mar. 10, 1970 ries away the dust. The location for the drill bit is shown at 18a in FIGURE 1.

On the edges opposite the piano hinge 16, namely the edges 20, 22, there is intermediate the end thereof disposed a clamp fastener 26 for retaining the mating construction in a closed position. Along the remaining edges of the open boxes 12, 14, there is a recess 40, 42, shown in FIGURE 3, formed by flanged U-shaped members 44, 46, 48, 50, as shown in FIGURE 2. U-shaped members 44, 46 collect heavy particles to be used in packing previous holes, and U-shaped members 48, 50 preserve the vacuum.

From the base of the attachments 10, there are provided spring coils 60, 62, 64, 66, of predetermined length and strength to provide support for the mating construction. Also provided is a felt sheet 70, 72 for each of the boxes 12, 14 forming the recess 42.

The basic structure of the attachment forming the mating construction may be fabricated from steel, or other material such as sheet tin, plastic or hard rubber. Other miscellaneous materials such as felt, forming the sheets 70, 72, may be contemplated, and coil steel springs are used for the support springs 66.

It is also within the contemplation of the present invention to provide a doughnut shaped mating construction in lieu of an open box type arrangement.

The invention may also be suspended from the drill rig head if so desired and without departing from the spirit of the invention.

What is claimed is:

1. An attachment for drilling equipment comprising a generally rectangular structure consisting of two separable half sections hinged along adjacent edges, fastening means for connecting the opposite edges to form a boxlike enclosure having an open bottom and an open top, inwardly extending spaced flanges surrounding the top and bottom openings, means defining an opening in the side wall of one half section adapted for the reception of a vacuum house, a felt sheet overlying the top opening of each half section, said sections having adjacent edges when the structure is closed between which a drill is adapted to be extended, legs depending from the under side of each section, and coil springs adapted to abut the surface to be drilled extending from the extremity of each leg.
